He is understood to have been found in Donegall Place, with paramedics spending more than 40 minutes with him at the scene.

His death on the streets of the city has resulted in outcry from many groups and calls for more to be done to help the homeless in Belfast.

In a Facebook post, Cafe Kelstar said: "We are so sad to hear the news that one of the homeless guys we have been in contact with has passed away.

"We would like to provide hotel accommodation for at least one homeless person per week/every week so they can have a sheltered nights sleep.

"For Jimmy this is too late. Let's hope we can help some one else though. If any organisation would like to get in contact with me just send me a pm."

Ciaran Kelly, who owns Cafe Kelstar, told the Irish News the death of the homeless man had hit home.

His business already provides hot food for rough sleepers in the city centre.

He added: "People are just so vulnerable in this tough economic climate. I know guys who had their own business who are now begging on Castle Street.

"People stereotype homeless guys. They haven't always been like that. There's thousands of small business and if everyone was to do something each week, it would eradicate the amount of people sleeping on the streets."
